Question

Why nuclear charge increases along group?​

Answer 1

Explanation:

in general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant. ... Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital.
